在马克思主义认识论发展史上,第一次对认识论进行较为系统阐述的当然是毛泽东同志的《实践论》。《实践论》认为人的认识是从社会实践中得来的,人们在实践中得到对客观事物的丰富的感性印象,这是认识的第一个阶段——感性阶段。在这个阶段,人们还不能造成深刻的概念,作出合乎论理的认识,即认识客观事物的本质。社会实践的继续,使这种感性印象反复了多次,于是认识发生了一个质的飞跃,产生了概念。这是认识的第二个阶段——理性阶段。在这个阶段,人们对在感性阶段得到的材料进行加工改造,去粗存精,去伪存真,由此及彼,由表及里,从而形成概念,然后运用概念进行判断和推理,发现客观事物的本质和规律性。这样,一个 In the history of the development of Marxist epistemology, it is of course the “practical theory” of Comrade Mao Tse-tung that the first systematic epistemology should be elaborated. “Practice Theory” holds that human cognition is derived from social practice and that people get the rich, perceptual impression of objective things in practice. This is the first phase of cognition - the perceptual phase. At this stage, people still can not create profound concepts and make reasonable understandings, that is, understand the essence of objective things. The continuation of social practice made the perceptual impression repeated many times, so that a qualitative leap in understanding took place and a concept emerged. This is the second stage of understanding - the rational stage. At this stage, people process and transform the materials obtained during the perceptual period to create a concept by using rough concepts and excuses, by which to form concepts and then use concepts to make judgments and reasoning to discover the essence of objective things And regularity. In this way, one
